Hello. I'm a ruby newbie.
I'd like to make a "mass substitution" version of gsub, like in the sed
example:

$echo "ásturãkolsé" | sed -e 'y/áãé/aae/'
asturakolse

Alike, I'd do something like "ãolélü".gsubm("ãéü","aeu") which would
return "aolelu"

----->Code-1:
class String
def gsubm(letras_ruins,substituir_por_este_char)
resultado = self.split(//).each {|letra_do_self|
letras_ruins.split(//).each {|letra_a_substituir|
letra_do_self.gsub(letra_a_substituir.to_.join.squ eeze,substituir_por_este_char)
#.join.squeeze
#p 'ls:' + letra_do_self.squeeze
}
}
return resultado.join
end
end

p "Leeinád".gsubm("á",'a')a

----->Code-2:
p "leeináãd".sub(/[áã]/,'a')

I didn't get success in any case. I've searched a lot also, but couldn't
find any solution.
Thanks in advance for any .

Maybe tr will work for you:

irb(main):012:0> "abcdefghijk".tr "abc", "123"
=3D> "123defghijk"

It supports character ranges, and padding the second argument
with its last character if it's shorter than the first one:

"hello".tr('aeiou', '*') #=3D> "h*ll*"
"hello".tr('^aeiou', '*') #=3D> "*e**o"
"hello".tr('el', 'ip') #=3D> "hippo"
"hello".tr('a-y', 'b-z') #=3D> "ifmmp"

I was having some problems testing your cases, I think because of the
strange chars, maybe that's the source of your problems too?

Hope this s,

Jesus.

The "strange chars" are common chars in Brazilian Portuguese and
Portuguese as well as other languages. e.g.: francês, inglês, pátria,
nação, aeroviário, silábica, and so on.

Ruby wasn't designed to deal with those chars in the same way you can
deal with english-only chars.

"som".tr('sm','NM') #=> "NoM"
"cruxificação".tr("çã","ca") #=> "cruxificaaaaao"

$ ruby --version
ruby 1.8.6 (2007-09-24 patchlevel 111) [i686-linux]

Maybe it's better to use a system() call and execute sed or start
learning some other language like perl.

Thanks once again.

Have you tried setting the character set to Unicode? That can make a
difference. Also, before you abandon Ruby altogether, be aware that
Ruby 1.9 deals with characters completely differently than Ruby 1.8,
so those problems you're having might go away when you upgrade (not
necessarily now, of course, 1.9 being officially 'experimental')

I've tried this and still doesn't work as expected

jesus@jesus-laptop:~$ irb1.8 -KU
irb(main):001:0> "=E2bcd=EB".tr "=E2=EB", "ae"
=3D> "eebcdee"

Maybe someone can explain if this should work as the OP
and myself are expecting or not and why?

Jesus.

Thanks, Matz. This works:

jesus@jesus-laptop:~$ irb1.8 -KU
irb(main):001:0> require 'jcode'
=3D> true
irb(main):002:0> "=E2bcd=EB".tr "=E2=EB", "ae"
=3D> "abcde"

Although I don't understand all the nuances that are coming into play here.

This left me a bit nervous, but as I'm not in need of this (I'm not the OP)
I'll leave it for later when I have more time to understand more about
this issue.

Thanks for answering,

Jesus.

I should thank you three for the solution. It works in the manner Jesús
has posted. Thank you all.
